2004 Gmc Sierra Buildup American Racing Headers Long Tube Headers

OK, so we tackled fuel and air going into the combustion chamber, now we need to get all of that air out of the engine. To help our LSX376 breathe easy, we ordered a pair of American Racing Headers long-tube headers. These bad boys are made out of 304 stainless steel, feature 3/8-inch flanges and massive 17/8-inch primaries complete with hand-ported inlets. The primaries merge into a large 3-inch Y-pipe collector and will be connected to our Banks 3-inch Monster exhaust system. Another bonus, these headers are made right here in the U.S.A., and will fit lowered trucks, so our Project Novakane won't be having any clearance issues.
